Regulations BC5.2 regulations, made easy, 16.4 gaseous decontamination process of containment cabinets:
1. Concentration and Time: To start the process, a sterilant gas is injected into the sealed cabinet enclosure to create a specific concentration in the air. It is essential to wait until the gas has reached the desired concentration and exposure time for the gas to be effective. This will vary between fumigants.
2. Monitoring: An electronic monitoring system is used to measure the concentration of the gas. This step is crucial to ensure that the concentration and exposure time are optimal. If the concentration and exposure time are not correct, the biological kill may not be achieved.
3. Exposure Process: Once the gas has dispersed and reached the required concentration over time, the exposure process begins. This step is crucial to ensure that the gas is effective in decontaminating the area and inactivating any potential microbes and biological indicators.
4. Purging: After exposure, the decontamination gas is purged from the space through controlled ventilation. Suitable options for ventilation include an adjacent fume hood, canopy or carbon scrubber. By following these four essential steps, you can ensure that the gaseous decontamination process of containment cabinets is carried out safely and effectively.
